I'm assuming you did not cut open the main key that now only makes an electrical click and does not start the car. This sounds like the car battery is dead. If you did cut open the key then you might have damaged the EWS portion of the key that enables starting of the car. The key programming does not have anything to do with being able to start the car or the battery in the key. Key programming is only for syncing up the keyless entry buttons to lock, unlock and pop the boot remotely. For the key that you say only half works where it can open the boot and unlock the doors. It sounds like you might have damaged a component or two on the circuit board when you cut it open. Check out these pictures of some genius key repair work
